With a marriage contract forcefully done, he married her, and all she could do was comply, and resent him deeply for that and for all the following misunderstandings they faced.
However, it was already too late when she understood she actually loved him.

A cauldron, a secret forging method, and his blood created an ultimate weapon. The youngest Sword Crafting Master on Earth had been reborn from another world. With the Nine Yang Divine Furnace and a scroll of Divine Equipment, he was like a fish in water, standing at the pinnacle of the martial way. There were tens of thousands of clans, billions of cities, and countless experts. He was the master of ups and downs!

It was a passing wish to the weary and tired Eugene and she’d not think it’d ever come to pass… but it did.

She opened her eyes and found she was sent to a novel-like world she wrote in passing and became Jin Anika, the scorned queen notorious for her ruthlessness and undeserving of her status.

Queen Jin only sought and desired to see the destruction of this world — the villainess who met her untimely and miserable end at the hands of her husband, Kasser, the reigning king of the Fourth Kingdom.

While struggling to survive in the unknown world, King Kasser visited Eugene and demanded that a contract be fulfilled and come to fruition.

“Three years ago, we made a deal.”

It turns out the Queen was under a contractual marriage with King Kasser. The ultimate price? To bear him a child.

“A… a child?”

“Yes, my successor.”
